IPC: H04L29/08
Filed: 2003-07-28
Granted: 2008-04-23
Abstract: A new data communication system is described which enables data transmission over existing telephone lines at rates higher than possible with existing methods, including conventional modems. By using a novel asymmetric configuration of the two communication endpoints, the currcntly-accepted maximum theoretical limits on the data rate are no longer applicable. One endpoint is connected directly to a digital telephone network, whereas the other endpoint uses a conventional telephone connection. This reduces the transmission problem to compensation for a single telephone line interface and a single analog local loop. Means of providing this compensation and the required clock synchronization were also created, enabling a practical implementation of the system. The new system can achieve rates up to 64,000 bits-per-second and has broad utility in several active areas including wideband audio transmission, video transmission, networking, facsimile transmission, and remote computer access.

Abstract: According to an aspect of the present invention, in a virtual space unit area, a message is distributed among computers using a physical topology based on a physical network. This avoids delaying operations in a computer which are related to those in another computer on a virtual space and taking a roundabout route on the physical network for distribution. On the other hand, outside the virtual space unit area, a message is distributed among computers using a virtual topology based on a virtual space. Consequently, the computers forming the physical topology can be limited to those present in the virtual space unit area. It is thus possible to reduce the amount of communication required to measure physical network distances.
